OIL-CUP FEEDER.

SPECIFICATION forming part of Letters Patent No. 447,300, dated March 3, 1891.

Application filed August l2, 1890. `Serial No. 361,807. (No model.)

To all whom, it may concern.'-

Be it known that I, JAMES S. DONNELLAN, a citizen of the United States, residing at Dubuque, in the county of Dubuque andState of Iowa, have invented a new and useful Oil- Cnp Feeder, of Which the following is a specification.

This invention relates to oil-cup feeders,

and is in the nature of a device adapted to io be applied to ordinary oil-cups or lubricators for machinery'for the purpose of conveying the lubricating material to the bearings; and

it has for its object to construct a feeding device in the nature of a wick in such amanner that the ow of the lubricating material may be regulated according to the season of the year and t0 the more or less heated state of the bearings when the lubricating material is in a more or less liquid state.v

2o The invention consists in a compound wick made of Wire and of worsted or other yarn, in the manner and for the purpose which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a vertical sectional view ot' an 0il-cup equipped with a feeder constructed according to my invention. Fig. 2 is a perspective detail view showing the feeder detached and with parts broken 3o away to more clearlyillustrate the invention. Fig. 3 is a transverse'sectional view taken on the line 3 3 in Fig. l.

Like numerals of reference indicate like parts in all the figures.

l designates an oil-cup, which is of ordinary construction and. for which noV special novelty is herein claimed, said oil-cup being `composed of the base 2, having a screwthreaded nipple 3, the cup or glass 4, the top 4o 5, and the cover or plug G.

7 designates my improved feeder, Which is composed of a core S of wire,whicl1 is twisted so as to form at the ends thereof thev loops 9 9. Suitably attached to the said core are a series of strands l0 of Worsted or other yarn. Part or all of these strands are` permitted to project through the loop 9 at one end of the wire core, said strands being preferably threaded through the eye or loop at the op posite end of the core and doubled over the 5o latter and secured. In this manner a series, of ends (designated by ll) are caused to project from the loop at one end of the core. In the loop at the opposite end is tied a single strand of yarn, thus forming two projecting ends, (designated by l2.)

A portion of my invention is dependent upon the fact that While at one end of the core a number of the ends of the yarn exceeding two are permit-ted to project, at the 6o opposite end only two such yarn ends and no more are permitted to project. This may be modified to the extent that an unequal number of strands Without regard to the actual number shall be permitted to project at opposite ends of the core.

The operation of my invention will be readily understood. The feeder is introduced vertically throughthe lubricator or oil-cup," and one end of the same is caused to enter 7o the nipple at the lower end of the cup. When the end of the feeder having the larger number of projecting ends is thus introduced, the said strands will be folded up within the nipple, and will thus serve to partially check the flow of the lubricating material. If it shall be desired to increase the flow, the feeder may be simply reversed and the end having the less number of projecting strands be introduced into the nipple, the capacity of which 8o for the passage of lubricating material Will thus be increased.

Having thus described my invention, what I claim, and desire to secure by Letters Pat-ent of the United States, is- 8 5 l. A wire core twisted to form loops or eyes at opposite ends thereof, in combination with a covering of yarn threaded through said loops, substantially as set forth.

2. A core provided with loops or eyes at 9o its ends, in combination with a covering of yarn having ends projecting at one end of said core and a single strand of yarn tied in the eye at the opposite end of said core, substantially as set forth. Y 9 5 3. The combination, with alubricator or y oll-eup, of a. reverslble feeder and regulator my own I have hereto afhxed my slgnature 1n consisting of :t wire core having eyes 0r loops presence of two Witnesses.

at its ends, in coverin y of yarn threaded T T T through said eyes, and aan unequal number of JAMES S' DOLBELLAB 5 strands of yarn projecting at opposite ends, Witnesses:

suhstantallyas and for the purpose setforth. J. M. XVARREN,

In testimony that I claim the foregoing as J. I. MULLANY.
